[PATCH 1/3] mtd: nand: omap: Revert to using software ECC by default

2014-08-05 Thread Roger Quadros
For v3.12 and prior, 1-bit Hamming code ECC via software was the default choice. Commit c66d039197e4 in v3.13 changed the behaviour to use 1-bit Hamming code via Hardware using a different ECC layout i.e. (ROM code layout) than what is used by software ECC. This ECC layout change causes NAND files
